Abstract –For achieving the desired quality of SCC, proper
curing is essential. But in practice achieving proper curing is
difficult due to dependency on humans. Also requires water
daily during the curing period. Hence researchers are using
self curing compound. The effect of Self Curing Compound
PEG 400 on compressive strength of different grades of SCC
Mix is not investigated as per the literature cited. The
present investigation finds the effect of PEG 400 self curing
compound on compressive strength of SCC Mixes.
The Nan-Su mix design is used. The workability properties
Slump Flow, J-Ring satisfy EFNARC Guidelines, but V- Funnel
and L Box values does not satisfy EFNARC Guidelines. For
M25 and M30 grades compressive strength obtained is more
than the target mean strength. For all grades compressive
strength obtained is more than the characteristic
compressive strength of concrete.

1. INTRODUCTION
For achieving the desired quality of SCC, proper curing is
essential. But in practice achieving proper curing is
difficult due to dependency on human. Also requires water
daily during the curing period. Hence researchers are
using self curing compound. The effect of Self Curing
Compound on compressive strength of different grades of
SCC Mix is not investigated as per the literature cited. The
present investigation finds the effect of PEG 400 self
curing compound on compressive strength of SCC Mixes.
The Nan-Su mix design is used. Master Glenium SKY 8233
super plasticizer is used. Mix grades M20 to M40 are
considered in investigation.

Where,
C= Cement content (kg/m3);
f’c = designed compressive strength (psi). =6273 psi
(43.25 MPa Target Mean Strength Obtained from IS:
10262-2019)
Step 3: Calculation of mixing water content required
by cement:
(4)
Where,
Wwc = water required by cement (kg/m3),
= the water/cement ratio = 0.385 (After Trial mixes)
Step 4: Calculation of SP dosage
Dosage of SP used Wsp = n% × C (5)
Where,
n% = Dosage of SP = 0.8 % (Fixed after trials)
Amount of water in SP
Wwsp = (1-m%)Wsp = 1.255 kg/m3 (6)
Where,
m% = Amount of binders and its solid content of SP taken

Step 5: Calculation GGBS content:
[ ( )] =

Where, w = density of water,
Gca, Gfa , Gc, Gw are specific gravity of coarse aggregates,
fine aggregates, Cement, and water respectively,
(W/G) = Water to GGBS ratio(Assumed).
Va = air content in SCC (%).
The modified formula2
(8) for calculating WG is used.
* ( ) + (8)
Where, GG, Specific Gravity of GGBS
and = 0.385 is assumed, and VPG obtained from
Eq.(7)
WG = 202.235 kg/m3 (9)
Mixing water content required for GGBS paste is obtained
from Eq(10)
WWG = × WG =77.860 kg/m3 (10)
Step 6: Calculation of mixing water content in SCC:
The mixing water needed by SCC is calculated from Eq.
(11).
Ww = Wwc + WWG - Wwsp = 197.361 kg/m3 (11)
Step 7: Calculation of PEG 400 Self Curing Compound:
PEG 400 Self Curing Compound of 0.5% by weight of
Cementitious materials is calculated from Es. (12).
WPEG = .005x(C+WG)=0.005 x( 313.649+202.235) = 2.579

3. MIX DESIGN
Concrete grades M20 to M40 are designed as per above
Nan-Su mix design. Target mean strength as per IS
10262:2019 is used for the mixes in Eq. 3 in place of f’c.
Based on trial mixes W/C ratio and SP dosage is fixed to
satisfy EFNARC guidelines. The SCC mix proportions for
different grades of SCC are shown in Table 4.
4. WORKABILITY TESTS
Slump flow test and then J-Ring test is conducted in order
by using 6 litres of concrete. V funnel test is conducted by
using 14 litres of concrete. L Box test is conducted by using
17 litres of concrete. Fresh properties are determined for
the mixes. The results are as show in Table 5. Slump Flow
and T50 Slump Flow results are conforming to EFNARC
guidelines for SCC and other results are not confirming to
EFNARC guidelines.
5. COMPRESSIVE STRENGTH OF MIXES
The compressive strength of different grades of concrete
for 3,7 and 28 days is determined after curing in air at
room temperature and the results are shown in Table 6
and also shown in Fig 1. For grades M25 and M30
compressive strength is more than the target mean
strength. For all grades the compressive strength obtained
is more than the characteristic compressive strength.
